How Much HP

73 Mustang Boy · 09-20-2001, 06:06 PM

I have a 73 mustang that orginaly came with a 302. I blew the 302 up and built a 351W to put in its place. My motor is a 351W (bored .30 over), Comp cam with .488lift and 218dur, 1.7 ratio roller rockers, arround a 9.5 to 1 CR, Offenhauser dual plane intake, 600cfm Edlebrock carb, Headman Headers, 2.5in exhaust with 2 chamber flowmasters, MSD 6 ignition System, Ford GT-40 heads. I was just wondering if anyone knew how much HP this thing might be putting out. Thanks for your help

I'm thinkig 300-350 depending on how it's tuned. 600 cfm carb is a little small IMHO. I would get a 750 with vac secomndaries if it was me. Maybe a Holley or Demon.
